Overview

There are three pathological types of bronchiectasis - Tubular/Fusiform, Varicose, and Saccular. The location can be local or general.

Classification

Based on Severity

There are three types of bronchiectasis, varying by level of severity.

Type	Features
Tubular or Fusiform (cylindrical) bronchiectasis also known as follicular bronchiectasis (the most common type)	These are mildly inflamed bronchi that fail to taper distally
Varicose bronchiectasis	The bronchial walls appear beaded because areas of dilation are mixed with areas of constriction
Saccular (cystic) bronchiectasis	These are characterized by severe, irreversible ballooning of the bronchi peripherally, with or without air-fluid levels

Based on Location

• Localized

• Confined to one lobe

• Generalized

• Involves many lobes
